How low can municipal water conservation go?

From Gary Woodard’s work – in Arizona…

an annual drop in per-household demand of more than 2 percent between 2000 and 2013 across Maricopa and Pima counties.

This trend is expected to extend through 2020, as we continue to replace appliances, fixtures, and landscape plants with new, more water-efficient ones; construct new, more water-efficient homes; and participate in water conservation programs offered by municipal providers.



  1. Joe – Tucson reports 130, Albuquerque 134-135, but without doing more detailed reporting I’m uncomfortable with comparisons because of differences in the way the numbers are calculated (what’s included, what’s not, how wastewater is accounted for, that sort of thing). May not be apples to apples.

  2. I wonder how much of a mess persistent drops in usage will make of the water agencies’ finances.
